So just did some googling and got a pdf file downloaded. I dont remember which site I downloaded this, but its a very handy guide. You can download the Pdf from here by right clicking and selecting “Save target as” in IE and “Save link as” in Firefox. Hope it will be of some use to people who are unaware of such shortcut keys.
